Application filed November 29, 1918. Serial No. 264,562.

To all whom it may concern:

Be it lmown that I, EDUARDO GABRIEL LACOSTE, a citizen of Argentina,residing at Calle lilaipu 671, Buenos Aires, Argentina, have invented anew and useful Improvement in Orthopedic Chairs, of which the followingis a specification.

My present invention relates to an ortho pedic chair specially designedfor the use of patients suffering from coxalgia and congenital luXationand a substantial feature of said chair consists in that it offers tothe patient a maximum of comfort, allowing him to remain seated withoutcausing any pain to the affected part of his body, As will hereinafterbe seen, owing to the construction and general arrangement of the partswhich constitute the chair and in particular, of its seat, which allhave been devised to adapt themselves to the part affected by the abovediseases, a perfect rest is obtained, while absolutely avoiding, owingto an instability of the seat, any movements liable to hurt the diseasedpart.

The chair comprises a pyramidal framing with a movable chair back,having integral lower extensions on which is supported the legcorresponding to the side afiected by coxalgia. It further comprises twofalse or movable seats, to be used one or the other, according to thecondition of the disease, said-seats being arranged to actuate atdifferent degrees of height, adjustable at will, and in combination withsaid movable chairback and with arm rests arranged to be raised. Theframing is mounted on wheels and is suitably reinforced at its centralpart, in accordance with the size of the patient who is to use thechair. The front part of the chair, though provided with a shiftablecross stay, remains open, so that the invalid may sit down or risewithout diiliculty.

In order to facilitate a clear understanding of this specification,detailed drawings have been annexed thereto, in which:

Figure 1 shows a frontelevation of an orthopedic chair constructed inaccordance with this invention.

Fig. 2 represents a rear elevation of the same chair.

Fig. 3 is a lateral elevation which illustrates the movements of thechair back and arm rests.

Fig. 4 is a perspective of the special seat for double coXalgia andcongenital luXation.

Fig. 5 is a perspective of a seat for right or left co-Xalgia as well asfor the first stage of congenital luxation.

In said drawings, 1 indicates the four legs which form the mainsupporting frame or base of the chair, said legs being mounted on wheels2 and connected together by means of the cross bars 3 and 4 of which theupper one 4, at the front, is adapted to be raisech In the case ofchairs destined for adults, at the front an additional standard or fifthleg 5 may be arranged, in combination with the seat, so as to serve as afront support. Thechair-back 6 is conveniently hinged to the rear crossbar 7 and carries, by means of the plates 8, suitably curved in order toclear the hinges, the hanging extensions or supports 9, whereon is torest the leg of the invalid. The posiat the desired degree of height.Whichever of r the seats shown in Figs. 4 and 5 be adopted, the sameinvariably comprises a rod 15, arranged to slide within the said pipe13. The seat of Fig. 4, as has already been stated, is destined to beused in connection with congenital luxation; it consists of a centralpad 16, formed after the manner of a bicycle seat, and two lateral padsl7, 17, which by means of compass joints 18, 18 may be set at differentdegrees of incline, as may be required by each particular case. The seatshown in Fig, 5 consists of two tiltable parts 19, secured by" hinges tothe central part 20, in combination with means which allow of retainingthem in their horizontal position.

As already mentioned before, this seat has been specially devised forpatients suffering from right or left coxalgia. On lowering one of theparts, a lateral opening is left in the seat which allows of the readypasthe side where immo- The seat 111 its horizonfor the first stage ofsage of the leg of bility is required,

tal position serves congenital luXation.

Fig. 1 illustrates the said seat, suitably arranged for use inconnection with left coxalgia.

Up to this date, no orthopedic chair has been specially constructed forthe treatment of tl1(3tbOV8 said diseases, in spite of the considerablenumber of persons suffering therefrom.

It will be understood therefore, that when referring to the chair shownin the drawings, this is done by Way of example, since the details ofconstruction of the same may vary without altering the novelty of thein- 'ention. The essential features of this invention substantiallyreside in a chair, of any suitable form of construction, comprising asprincipal parts a chair-back of adjustable incline, with lowerextensions for the support of the legs, in combination with movable orfixed seats, comprising movable parts, all of which permits of anefiicient treatment of the afore mentioned diseases.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim, is:

1. An orthopedic chair, comprising, a sectional seat, leg supportsextending below and adjustable with relation thereto, and means forrendering one of the sections of the seat inoperative, whereby one ofthe leg supports is rendered operative.

2. An orthopedic chair comprising an adjustable seat, an adjustable backhaving leg supporting portions extending below the seat, and means foradjusting the seat whereby the supports are accessible to the legs.

3. An orthopedic chair for invalids, comprising a seat iaving adjustableportions, a pivoted back having portions extending below the seat, andmeans for adjusting the seat portions to permit access of the legs tothe extending portions.

l. An orthopedic chair for invalids comprising a seat having lateralhinged portions, a pivoted back having leg supporting portions extendingbelow the seat, means for inclining the back and leg supports, and meansfor angularly displacing said hinged portions.

5. An orthopedic chair for invalids comprising a seat having lateralhinged portions, means for raising and lowering the seat, a combinedback and leg support pivotally mounted behind the seat and extendingabove and below the latter, means for adjusting the inclination of saidsupport, pivoted arm rests on either side of the seat, and means forangularly adjusting said lateral portions for the purpose specified.
